Fitbit Integration - Write Water intake via API

There are a few items in the Fitbit app that require the user to enter some information, i.e. Calorie tracking and Water intake.
I am wondering if it is possible for the integration to allow the user to enter the information for these values, rather than having to enter them into the app, then view them in the integration.
What I am hoping to accomplish is to create an NFC tag that will add 16oz (or other amount) of water at each scan.
If this is possible, I would like to do something similar with meal prep, and set NFC tags with certain calorie counts.
